Second-order Affordances: Design & Quantum Superposition

A few years ago, having read a thought-provoking article by Csongor Bartus I wrote about design & quantum superposition. The main idea behind this article, and my interpretation, is that - similar to a particle, which exists in a state of quantum superposition - a design doesn't exist by itself but can only ever be realised in a given context and at a specific moment through observation by a user and possibly a device that design is observed with. The gist, ... Read more

Image Compression Utility: Squoosh

When working with images on web applications and websites optimising images and reducing their download size is a quick win in terms of optimising page and app load times. There are plenty of image compression utilities out there - both web apps and tools for local installation. Recently, I've tried out several of those again because I wanted to reduce the overall load time of this website and according to website audit tools such as Lighthouse image sizes definitely was an area ...

Latency by The Radiophonic Workshop

On the 22nd of November, the electronic music pioneers of the BBC's Radiophonic Workshop (of "Doctor Who" theme music fame, amongst others) performed a unique piece of music called 'Latency', in which they make clever use of network latency to create a musical loop. Each of the musicians involved sequentially played his part in a loop. The result then was sent via the Internet to the next musician at another location, who in turn built upon what had been played until ... Read more

Reprise: Petro Salema – Storyteller Extraordinaire

Almost five years ago I wrote about a talk given by Petro Salema at that year's edition of beyond tellerrand in Düsseldorf: Petro Salema – Designing Interfaces That Think @ beyond tellerrand Düssedorf 2015 A common advice given regarding talks and presentations, especially ones of a more technical variety, is to not just talk about technical details but to tell a story. While this piece of advice is good and well-intentioned it's not usually exemplified or specified in any more detail. Steve Jobs is ... Read more

HTTP and REST Standards, Protocols and Headers for More Secure and More Robust Applications

Standards.REST is a website that helps you create better, more robust HTTP- and REST-based applications by providing an overview of existing, proven standards that allow you to build on existing solutions rather than re-invent the wheel yourself. The list of standards mentioned includes OAuth 2.0, the HTTP Caching standard and Application-Level Profile Semantics (ALPS), which - among others - is used extensively in Spring Data REST and Spring HATEOAS. On a closely related note, Stefan Judis published an article on HTTP headers ... Read more
